Diagnosis and Treatment of Voice Disorders.

Intro -- 1Formation of the Larynx: From Hox Genes to Critical Periods Jeffrey T. Laitman Drew M. Noden Thomas R. Van De Water   The human larynx is a compact and complex structure that must serve respiratory, protective, and vocalization functions. Although there have been several descriptions of the major histogenic and morphogenic events during laryngeal development in humans1 and other mammals,2 only recently have accurate fate mapping and molecular expression data become available. The larynx arises -- 2Laryngeal Development David H. Henick   The critical stages in the prenatal development of the human larynx provide valuable insight into the anatomy and clinical malformations of the mature larynx. Earlier theories of laryngeal development espoused the concept of a tracheoesophageal septum. Observations of laryngeal development over the past 2 decades challenge the validity of these earlier theories. Computer-generated solid-model three-dimensional reconstructions have allowed for a more preci -- 3Anatomy of the Human Larynx Clarence T. Sasaki Nwanmegha Young Hiroumi Matsuzaki Boris Paskhover   The human larynx functions as a complex sphincter that directs both airflow and bolus transport at the junction of the digestive and lower respiratory tracts. The larynx has evolved to fulfill 3 obligations.1 First, the larynx protects the airway during swallowing. Second, the phasic contraction and relaxation of laryngeal muscles during inspiration and expiration modulate airflow to the lungs. La.

4Functional Fine Structures of the Human Vocal Fold Mucosa Kiminori Sato   Viscoelastic properties of the lamina propria of the human vocal fold mucosa determine vibratory behavior and depend on extracellular matrices, such as collagenous fibers, reticular fibers, elastic fibers, glycoproteins, and glycosaminoglycan. The 3-dimensional structures of these extracellular matrices are indispensable to the viscoelastic properties of the vocal fold mucosa. Fine structures of the vocal fold mucosa infl -- 5The Microanatomy of the Vocal Fold Musculature Ira Sanders   The object of this chapter is to describe the neuromuscular organization of the larynx, especially as it relates to voice production. The initial part of the chapter reviews the course of the main laryngeal nerves and the innervation and function of each muscle. The second part presents a hypothetical overview of voice production based on what is being learned about the anatomy of the laryngeal muscles. The descriptions depicted here -- 6Vocal Fold Extracellular Matrix and Wound Healing Marie E. Jetté Susan L. Thibeault INTRODUCTION The source-filter theory1 of speech production models speech as a combination of source signal (the glottal source, most commonly vibrating vocal folds) and a linear acoustic filter (the vocal tract). According to this theory, alterations in vocal fold vibration or vocal tract characteristics will affect acoustic output. The cover-body model2 is commonly used to describe the vibrational properties o.

7 Benign Vocal Fold Pathology Through the Eyes of the Laryngologist John S. Rubin Eiji Yanagisawa   This chapter is dedicated to the memory of Steven Gray, a great pioneer into the causes of benign vocal fold pathology. There are numerous causes of benign vocal fold pathology. Because the laryngeal tract can only respond in certain ways, the symptoms produced are limited, and the resultant clinical dysphonia depends more on the degree of air-wasting, contact of the vocal folds, and alteration of -- 8 Laryngeal Function During Phonation Ronald C. Scherer INTRODUCTION The larynx performs many functions to aid communication and allow life. As an open flow valve, it permits breathing,1,2 blowing, and sucking, as well as yawning,3,4 voiceless consonant production,5 and musical instrument playing.6-8 As a transient closed valve, it produces coughing and throat clearing.9 As a prolonged closed valve, it participates in swallowing10,11 and effortful behaviors such as lifting, defecation, and the l -- 9Laryngeal Neurophysiology Christy L. Ludlow INTRODUCTION Laryngeal neural control is evident when viewing the vocal folds on nasoendoscopy, listening to the voice, or evaluating respiratory function. Although the motor and sensory innervation are relatively well understood, vocal fold motion is dependent on the integration of several levels of control in the central nervous system (CNS) that are less well understood and in some cases unknown. This chapter reviews what is known about components.

10 The Neurology of Stuttering Savita Kumari Rebecca Spain Steven Mandel Robert T. Sataloff   What do singer Carly Simon, Chicago Bulls basketball player Bob Love, NBA all-star and sports broadcaster Bill Walton, actress Marilyn Monroe, author John Updike, and politician Sir Winston Churchill have in common? All were stutterers, and all were able to achieve successful public careers. Actors Bruce Willis and Julia Roberts and professional golfer Tiger Woods have admitted that they had a stutterin -- 11 Toward a Dynamical Diagnosis of Vocal Function R. J. Baken Robert F. Orlikoff INTRODUCTION There is an extraordinarily large array of tests and techniques available to both the researcher and practicing clinician for measuring the acoustic and physiologic aspects of vocal behavior and for characterizing and classifying the resultant voice signal. A fair number of assessment methods find application in the everyday evaluation of phonatory dysfunction. For many years, a significant portion of t -- 12 Research in Laryngology Gayle E. Woodson   The birth of laryngology as a specialty was enabled by the introduction of a new technology: mirror laryngoscopy. This indirect means of viewing the larynx was developed by a singing teacher but was quickly adopted by physicians. Suddenly, the phonatory mechanism could be studied. It was possible to detect a physical basis for hoarseness in many patients and to observe changes in response to treatment. Throughout its history, the development of laryn.

13 Patient History Robert T. Sataloff   A comprehensive history and physical examination usually reveals the cause of voice dysfunction. Effective history taking and physical examination depend on a practical understanding of the anatomy and physiology of voice production.1-3 Because dysfunction in virtually any body system may affect phonation, medical inquiry must be comprehensive. The current standard of care for all voice patients evolved from advances inspired by medical problems of voice p -- 14 Physical Examination Robert T. Sataloff PHYSICAL EXAMINATION A detailed history frequently reveals the cause of a voice problem even before a physical examination is performed. However, a comprehensive physical examination, often including objective assessment of voice function, also is essential.1-3 In response to feedback from readers of the previous editions, this chapter has been expanded to include a brief overview of objective voice assessment, and other subjects covered more comprehens -- 15Evaluation of Laryngeal Biomechanics by Transnasal Flexible Laryngoscopy Jamie A. Koufman   Biomechanical analysis of the performance of athletes has become common and is accomplished by linking a video system to a computer system so that movement can be evaluated critically in ultra-slow motion, frame by frame. With this approach, patterns of movement can be identified that are, at one extreme, optimally efficient and, at the other extreme, maladaptive, or even abusive. Using similar methods,.

16Transnasal Esophagoscopy Nancy L. Solowski Gregory N. Postma INTRODUCTION Transnasal esophagoscopy (TNE) is recognized as a valuable diagnostic and procedural tool in otolaryngology practice. It permits visualization of the esophagus to assist in the diagnosis of common otolaryngologic complaints, such as dysphagia, globus pharyngeus, and reflux. It is also used in screening of patients with head and neck cancer. A major advantage of TNE is that it is performed in unsedated patients, without t.

This classic reference provides comprehensive, multidisciplinary coverage of the basic science and characteristics of voice disorders; diagnostic procedures and techniques; assessment protocols; as well as surgical and nonsurgical treatment models. This edition is completely updated and includes 10 new chapters. It will once again serve as a definitive reference for students and professionals in the fields of otolaryngology, speech-language pathology, voice and singing, and related sciences.
